12.6.2
Program Security
You can set separate passwords for ladder programs and motion programs. A lock mark is dis-
played for each password-protected program. To edit a password-protected program, you
must first enter the password.
The purpose of this password is to control access for editing. It does not affect the manage-
ment of program files (copying, cutting, pasting, deleting, or enable/disable settings).
This section describes the security that is provided, using a ladder program as an example.
Setting the Password
1.
In the Ladder Pane, right-click on the program for which you want to set a password.
Select
Set the Password
from the pop-up menu.
The Program Password Dialog Box will be displayed.
2.
Enter 1 to 8 alphanumeric characters in the
New Password
Box. Enter the same pass-
word again in the
Password (Confirm)
Box, and then click the
OK
Button.
Note: 1. The
OK
Button will be enabled when one or more characters are entered in the
Password (Con-
firm)
Box.
2. The password is not case sensitive.
The Program Password Dialog Box will be closed, and a padlock icon will be displayed next to the
ladder program that was selected in Step 1. If the program was displayed in the main window, it will
be closed.
If you forget the password that you set, there is no way to recover it, and it will be impossible to
open the password-protected program.
